Since this is a patch for glibc, as well as that the cause lies there; I'll let the core system maintainers take a look at this first as to determine whether this is something to be fixed by glibc upstream or by the JRE upstream, or whether we can patch this at Gentoo. Since this new glibc version has affected multiple other packages (eg. acroread segfault) and I haven't heard of a documentation or announcement wrt a change in usage yes; I'm assuming that this is a glibc issue, if that's not the case then feel free to elaborate. Thank you.

(In reply to Tom Wijsman (TomWij) from comment #1)
This seems to be the same issue as Acroread (but here with an IMHO really weird patch) and it is fixed with glibc-2.19.

we're not merging that patch.  sounds like the JRE is broken.
